17 Claims.

The present invention relates to improvements in tabulating machines,and more particularly refers to machines of the type disclosed inLetters Patent of the United States No. 1,822,594, issued September 8,1931 to C. D. Lake.

Machines of the type disclosed in this patent are well known in the artand are adapted to analyze record cards having control points orperforations thereon. Such machines, after analyzing the control points,may print all or a part of the data on a suitable record material orthey may print data from each card and the total of such data for eachgroup by cards. They may accumulate the data from successive cards,printing the total accumulated from all of the cards, or from aparticular group of cards. These machines are quite flexible and othersimilar combinations may be effected.

In the machines disclosed in the above mentioned patent, the groupnumbers as taken from the card directly control the printing mechanismof the machine to print the group number from the rst card of eachgroup. After the first card of a group has been analyzed and the groupnumbers thereof printed, the machine proceeds successivelyto analyze theremainder of the cards in that group and upon a change of groupdesignating numbers the tabulating machine automatically is brought to astop and a total taking and resetting operation is initiated to printthe total standing on the accumulator which total is the total dataaccumulated from the group, and to reset the totalizers to zero.

One object of the present invention is the provision for printing thegroup number from the first card of each group while suppressing theprinting of the total data accumulated from said group until the totalof said data has reached a predetermined amount.

Another object is the provision for printing the group number from thefirst card of each group and suppressing the resetting of the totalizersuntil a predetermined amount has been accumulated thereonA I Stillanother obect of the instant invention is the provision of meansoperated under the control nf the accumulator wheels to suppress readingthe accumulator until the total standing thereon has reached apredetermined amount.

A further object is to suppress resetting the accumulator until thetotal standing thereon has reached a predetermined amount.

Various other objects and advantages of the invention will be obviousfrom the following particular description of one form of mechanismembodying the invention or from an inspection of the accompanyingdrawings; and the invention also constitutes certain new and novelfeatures of construction and combination of parts hereinafter set forthand claimed.

Fig. 7 is a conventional illustration of the circuit diagram.

General description In order to understand the significance of theinstant invention as applied to a machine of the type disclosed in theabove mentioned patent, it should be borne in mind that such machinesare adapted to be controlled to make listing operation and tabulatingoperation. The machine is controlled for listing operation to print theindividual items with the group numbers and then prints the totals ofthe items without printing the group numbers. When controlled fortabulating operations, the group numbers and totals only are printed. Afacsimile of a record sheet prepared on a machine controlled as setforth above is illustrated in Fig. 6.

In certain organizations it is not desired to print the total of eachgroup unless the total is equal to or greater than a predeterminedamount. In this case the group number is printed when the rst card ofeach group is tabulated, but the total for the groups is not printedunless it equals or exceeds the predetermined amount. 'I'he machine willcontinue tabulating successive groups of cards, printing the groupnumber of each group, until the amount accumulated equals or exceeds thepredetermined amount, whereupon, the machine is automatically controlledto make a total printing and resetting operation during which the totalis read from the accumulator, and printed in line with the last printedgroup number, and the totalizer then reset to zero. As an example torillustrative purposes let it be assumed, that a machine embodying thepresent invention is to be used in a railroad freight office whereinrecords are made of freight shipments including, the stations from andto which each shipment isy made, the weight of each shipment and therevenue derived therefrom. Figure 4 is a facsimile of a record preparedon such a machine.

In this case the railroad does not wish to record the weight of, andrevenue derived from individual or group shipments of less than, forinstance, 2,000 pounds. However, it is desired to indicate the shippingpoint and destination of each group or shipment. By using our device ona tabulating machine, characters designating the stations for each groupare printed, but the total revenue and the total weight for each groupare not printed until the total accumulated weight equals 2,000 poundsor more.

Referring to Figure 6 it will be noted that the two left hand columnsare marked Stations, From and To, the next column to the right is markedRevenue and the right hand column is marked Weight, In the stationcolumn marked From characters are printed indicating the station fromwhich the shipment was made, and similar characters are printed in thestation column marked To indicating the destination of the shipment. Onthe facsimile (Fig. 6) there are printed opposite the stationdesignations for each group or shipment, the revenue and weight. Forinstance, on the first line a shipment was made from station 890 tostation |23 weighing 567 pounds and from which shipment a revenue of$89.12 was received. The second line records a shipment from station 234to station 561 comprising 1802 pounds of freight which brought therailroad a revenue of $46.90. Line 3 indicates that the next group ofcards run through the tabulating machine represent a shipment of 1780pounds from station |23 to station 456, the revenue therefor being$24.68. It will be noted that each of these shipments were less than2,000 pounds.

Referring now to Figure 4, which represents a record sheet prepared onour improved tabu- Iating machine, it will be noted that the samestation numbers are printed on the rst three lines in columns 1 and 2 asare set forth above. However, neither the revenue nor the weight of therst shipment were printed on the rst line since the Weight was less than2,000 pounds. These amounts are entered into the totalizers but sincethe total weight at the end of the group was less than 2,000 pounds thetotal printing was suppressed.

During the listing of the second group the total weight accumulated onthe totalizer passed 2,000 pounds. At the next group change, therefore,under the control of the mechanism comprising the present invention, theweight and revenue totalizers are cleared and the totals standingthereon printed in the proper columns.

In case the Weights represented by two groups f of cards do not bringthe total Weight to 2,000

pounds or more, the next group is accumulated, and as many additionalgroups as are necessary to bring the total Weight to 2,000 pounds.

The circuit diagram (Fig. 7) is substantially the same as that shown inthe above mentioned Lake patent. During tabulating operations themachine is driven by a tabulating motor TM (Fig. 7) under the control ofthe usual cam controlled and relay controlled circuits indicatedgenerally at I0. During reset operations the machine is driven by areset motor RM4 under the control of a group of contacts and relaysindicated generally at Il.

When the machine is operated by the tabulating machine motor TM, theusual tabulating cards bearing differentially arranged index points orperforations, are fed past sets of upper analyzing brushes UB and then,exactly one card cycle later the cards are fed past lower analyzingbrushes LB.

As the perforated cards are fed past the lower brushes the perforationsthereon permit instantaneous closing of circuits to energize accumulatormagnets |2. The timed energization of these magnets control mechanismwell known in the art, to enter data interpreted from the card onto theaccumulator wheels.

The accumulator is of the typedisclosed in U. S. Patent No. 1,379,268issued to C. D. Lake, May 24, 1921, and which includes gears l5 (Fig.3), rotatably mounted on a reset shaft I6 suitably supported in themachine. These gears mesh with and are driven, under the control of themagnets I2, by gears |1 mounted on a shaft I8. An indicator Wheel |9,having indicia engraved, or otherwise suitably marked thereon, issecured to each of the accumulator gears |5 to enable the operator toread the data standing on the accumulator, directly therefrom through aconvenient sight opening 20 in the casing 2|.

The printing mechanism (Fig. 5) is substantially the same as that fullydisclosed in Lake Patent No. 1,822,594 and, described briefly, includesa plurality of type elements 22 slidably mounted in the enlarged upperend of a type carrier 23. The type carrier is guided near its upper andlower ends to permit vertical movement for the purpose of selecting thetype elements 22 for operation.

To effect the vertical reciprocatory movement of the type carrier 23 ontabulating operations a cam 24, secured on a shaft 25, is provided witha cam groove 26 embracing an anti-friction roller 21 on an arm 28pivoted on a shaft 29. An adjusting screw 30 carried by the arm 28cooperates with one arm of a lever 36 fast on the shaft 29. A short link31 connects an arm 38 also fast on the shaft 29 to a printer cross head39. Guide bars 40 are provided to guide the cross head 39 in itsvertical travel.

The configuration of the cam groove 26 is such that upon one rotation ofthe cam 24 it imparts to the arm 28, the lever 36. shaft 29 and the arm38 an invariable excursion first clockwise and then counterclockwise tonormal position.

This movement is communicated by the link 31 to the cross-head 39imparting thereto a vertically reciprocatory movement.

The cross-head 39 is actuated on total printing operations by a cam 4|and a total shaft 42. This cam 4| cooperates with a roller on an arm 43pivoted on the shaft 29. A projection on the arm 43 cooperates with anadjusting screw on the other arm of the lever 38. Thus, on totalprinting operations, the cam 4| acting through the arm 43 rocks thelever 36, shaft 29 and the arm 38 to impart to the printer cross-head 39its regular excursion.

The type carriers 23 rest on spring held ngers |43 pivotally supportedon projections |39 forming a part of the cross-head 39 so that the typecarriers travel upwardly with the cross-head for the purpose of carryingthe type elements 22 past a printing point on a platen 42 in synchronismwith the passage of the card by the lower brushes LB (Fig. 7). Ii', asthe card travels past the lower brushes, a control point comes intoregistry with one of the brushes the upward travel of the type carrieris arrested with the particular type 22 corresponding to thedifferential location of the control point on the card in printingposition.

The device for arresting the upward movement of the type carriers 23 insynchronism with the passage of the card by the brushes LB and, on totalprinting operations, in accordance with the amount standing on theaccumulator wheels includes a spring pressed stop pawl 44 (Fig. 5)normally held in ineffective position by a detent 45. Both the stop pawl44 and the detent 45 are pivotally supported on a cross bar 46 suitablysupported in the machine. A link 41 connects the detent with an armature48 associated with a printer magnet 49. It is to be understood thatthere is a type carrier 23 and a printer magnet 49 for eachdenominational order of the accumu-lator.

When the printer magnet 49 is energized either under the control of acard or on total printing operations, under the control of the usualimpulse emitter 50 (Fig. 7) controlled by the totalizers, it attractsthe armature 48 (Fig. 5). This draws the link 41 toward the right (Fig.5) rocking the detent 45 counterclockwise to release the stop paw] 44which, under the inuence of its spring, immediately engages the properone of a series of notches in the right hand edge of the type carriers23 in order to stop the carrier in a position commensurate, ontabulating operations, with the position of the control point on thecard, or, on total printing operations, in a position commensurate tothe setting of the corresponding accumulator gear I5.

Group control It is well known in the art that machines of this type maybe organized to automatically stop the listing or tabulating operationand to start a total printing operation when the control perforations ontwo successive cards do not agree. 'Ihe means for initiating such anautomatic group control involves a group control circuit such as isdisclosed in the above referred to Lake Patent No. 1,822,594, whichcircuit, described briefly includes magnets 5| and contacts 52 (Fig. 7)adapted to be plugged between the upper and lower brushes. The purposeof the contacts 52 is to open after the magnets 5| are energized inorder to take the arc from the brushes. Energization of the magnets 5|closes corresponding contacts 53, thus establishing the so-calledcontrol circuit which extends serially through all contacts 53. Thiscircuit is established in each card cycle so long as the controlperforations on each two successive cards agree. So long as this controlcircuit is made the machine will continue uninterruptedly to tabulatethe cards passing through the machine.

However, if one or more group control perforations do not agree on twosuccessive cards,

the corresponding magnets 5| are not energized and their contacts 53 arenot permitted to close. Thus the group control circuit is o-pen and atthe end of the card cycle the machine is controlled to initiate a totalprinting operation, during which operation, the amount standing on thetotalizer wheels I5 (Fig. 3) is read off from the wheels, set up on thetype carriers 23 (Fig. 5) and printed. The totalizer is then reset tozero.

The machine may be controlled to proceed automatically from a tabulatingcycle or operation into a total printing operation, and from a totalprinting operation into the tabulation of the next succeeding cardgroup.

The mechanism whereby a total printing and resetting operation isinitiated automatically will now be briefly described.

When one or more group control numbers or perforations on two successivecards do not agree and the corresponding contacts 53 remain open, asabove set forth, a magnet 6|, known herein as the Group control magnet,becomes deenergized upon opening of test contacts 62 near the end of atabulating operation. The magnet 6| is normally energized on tabulatingoperations, holding its armature 63 against the upper contact tomaintain magnets 65 and 66 deenergized. So long as the magnet 65 isdeenergized an operating circuit is maintained through the tabulatingmotor. This circuit extends through the tabulating motor TM, a startrelay coil |60, the clutch coils 11, motor relay coil |6|, contacts |62closed upon energization of coil |6| to form a holding circuit for saidcoil, upper card lever contacts |63, the contacts of coil 65, wire |64,the normally closed stop key contacts |65, cam contacts P3 to the otherside of the line. This circuit maintains the tabulating machine motor TMrunning as long as cards are passing the upper card lever.

However, when a group change Occurs and the magnet 6| is deenergized,its armature 63 drops into contact with the lower contact energizing themagnets 64 and 65. The magnet 65, when energized, attracts its armaturethus opening the circuit through the tabulating motor TM. Thisdeenergizes clutch magnets permitting contacts 'I8 to close establishinga starting circuit through the reset motor RM, whereupon, at the end ofthe current tabulating operation, the machine proceeds into a resettingand total printing operation. The starting circuit through the resetmotor RM extends as follows: Through the reset motor RM, reset clutchmagnets |66, contacts 18, wire |61, cam contacts L| now closed,automatic reset switch, stop key contacts |65, cam contacts P3 to theother side of the line. Energization of clutch magnets |66 closescontacts |68 setting up a holding circuit through the reset motor RM,clutch magnets |66, contacts |68, wire |69, cam contacts L2 to the otherside of the line. This circuit keeps the reset motor operating untiljust before ythe end of the reset cycle when contacts LPT, closedeenergizing magnets 64 and 65 which drop their armature closing theirrespective contacts. This sets up a shunt circuit around the resetclutch magnets IE6 through contacts Pl closed shortly after thebeginning of the reset cycle, contacts 64a, wire |69, contacts L2 to theother side of the line, deenergizing the reset clutch magnets |66. Thisopens the contacts |68, the reset motor, however, continues to run untilthe end of the reset cycle when the cam contacts PI open. If the autostart switch is closed the tabulating motor TM will again be energizedwhen the relay 65 is deenergized closing its contacts 65a, and when theP3 contacts are closed near the end of the reset cycle.

In order to read off the total standing on the totalizer a frame 54(Fig. 3) secured on a rock shaft receives an invariable excursion firstcounterclockwise and then clockwise to normal position at each totalprinting operation. The shaft 55 may receive its oscillatory movementfrom any suitable source preferably that disclosed in the abovementioned Lake patent.

A number of feeler fingers 56 are loosely mountcd on the shaft 55 andare resiliently urged counterclockwise against the bail |54 of the frame54 by springs 51 each having one end secured to an angular plate |55fast on the bail |54 and the other end anchored to a projection (notshown) on the rear end of its corresponding finger 56. At their outer orfree ends the fingers 56 carry adjusting screws 58.

Stepped cams 59 mounted on a shaft 60 are adapted to rotate in theplanes of the corresponding screws 58 (see Fig. 1). Gears 66 attached tothe cams 59 mesh with the gears |1 which in turn mesh with the totalizergears 15. Thus the gears 66 and the cams 59 are set to positionscorresponding to the setting of the totalizer gears.

As the shaft 55 rocks counterclockwise, the fingers 56, due to thesprings 51, are carried therewith until the screws 5B come intov contactwith and are arrested by the stepped cams 59.

The frame 54 continues its invariable excursion carrying therewith acontact 61 mounted on the rearwardly extending part of said frame. Whenthe movement of the fingers 56 is arrested by contact of its screw 58with the corresponding cam 59, the contact 61, continuing itscounterclockwise movement with the frame 54 about pivot 55, wipes ontothe curved end of an arm 68 carried by but insulated from the nowarrested finger 56. This, by means of another contact 69, closes acircuit through the printer magnets 49 (Figs. 5 and 7) for thatdenominational order, and, since the nger frame 54 is rocked insynchronism with the upward movement of the type carrier 23, themovement of said type carrier is arrested as the particular typecorresponding to the setting of the totalizer gear arrives at theprinting point. The total standing on the totalizer is then printed andthe totalizer then reset to zero in the usual well known manner.

Before the printer magnets 49 can be energized on total printingoperations it is necessary to close contacts 18 (Figs. 1 and 7), a pairof which contacts is-associated with each counter. The contacts 10normally are closed manually as a preliminary to operation of themachine when it is desired to automatically initiate a total printingand resetting operation upon the occurrence of a group change. This isaccomplished by shifting the knurled collar 1| (Fig. 1) toward the rightto couple the reset shaft 12 to the reset gear 13. An annular groove 14in the coupling 15 embraces one arm of a bell crank 16 rocking said bellcrank clockwise. The rounded end of the other arm of the bell crank,upon clockwise movement thereof, closes the contacts 19.

However, if the total printing and resetting are controlled by themanually set knobs 1|, the totals will be printed and the totalizersreset at each card group change. Since it is an object of this inventionto suppress total printing and resetting the totalizers until the weightof shipments equals or exceeds 2,000 lbs., other means is provided tooperate the reset clutches 15 (Fig. 1) and to prevent nergization of theprinter magnets 49 until the card group change succeeding theaccumulation of 2,000 or more on the weight totalizer.

This means includes magnets 19 (Figs. 1 and '7). Means is provided underthe control of the weight totalizer to energize the magnets 19 therebyto effect automatically the energization of the printer magnets when theregistered weight equals or exceeds 2,000 pounds. This means includes amagnet 86 and a magnet 81. These magnets are wired in series and areconnected to the line through a normally closed switch 88 and areadapted to be energized through a pair of contacts 89 operated by theweight totalizer. The contacts 89 are closed when the 1000denominational order totalizer wheel passes from 1 to 2 by mechanism tobe described later. These contacts when closed set up a circuit throughthe switch 88, magnet 86, magnet 81, contacts 89, wires and 92 to theother side of the line. This circuit energizes magnets 86 and 81.

It may be stated here that by opening the switch 88 the machine may bemade to function in its normal manner, printing the totals and clearingthe totalizers at each card group change.

Energization of the magnet 81 closes contacts 90 setting up a holdingcircuit through switch 88, magnet 86, magnet 81, contacts 90, camoperated contacts 9| and wire 92 to the other side of the line. Thisholds the magnet 86 energized which holds its contacts 93 closed toenergize the magnets 19 upon closing of their respective contacts LP8,LP9 and LP|0. These contacts close early in a reset operation and remainclosed until near the end of the cycle.

It is to be understood that the magnets 86 and 81 Will not be energized,and consequently the contacts 93 will not be closed to energize magnets19 unless the contacts 89 are closed at some point during the tabulatingof a group of cards, and, as

above stated this can only occur when the 1000 denominational ordertotalizer wheel of the weight totalizer passes from 1 to 2. Themechanism whereby the contacts 89 are closed under the above conditionis described as follows:

A rock shaft 94 (Figs. 1 and 3) suitably supported in the machinecarries an arm 95 extending horizontally toward the right (Fig. 3), thefree end of which arm rests above the insulated upper blade for thecontacts 89. Two arms 96 and 91 secured to the shaft 94 between themcarry a bail or rod 98 extending across the planes of the stepped cams59 for the 1000 to 10,000,000 denominational orders, inclusive. Springs99, only one of which is shown (Fig. 3), urge the arms 96 and 91 and therod 98 in a counterclockwise direction, which movement is limited by anarm |00 secured on the shaft 94 resting against a stop stud |0|.

Obviously clockwise movement of the bail 98, shaft 94 and arm 95 fromthe positions in which these parts appear in Figure 3 will close thecontacts 89 thus setting up the condition to render the total printingand resetting mechanism effective as set forth above.

The stepped cams 59 are shown in their 0 position in Fig. 3, and when anamount is added thereon, these elements are rotated counterclockwise asviewed in this figure. It will be noted by examination of Figures 2 and3 that the rod 98 has a notch cut therein opposite the 1000denominational order cam 59. Also that the bottom of the notch isequi-distance with the next step on the cam 59, which step representsthe 8 position with respect to the feeler finger 56, from the center ofthe shaft 60. Consequently the thousands cam plate 59 may be advancedone step to add one thousand onto the totalizer without disturbing therod 98. But if the thousands order cam 59 is advanced to the 2 positionthe rising face |02 between the 8 and 9 position on the cam 59 rocks therod 98, shaft 94 and arm 95 clockwise to close the contacts 89.

Should the stepped cam 59 for the 1000 orders be advanced from the or lposition to the 3 position at one continuous movement the rod 98 andshaft 94 would be rocked clockwise to close the contacts 89, and thenimmediately counterclockwise to normal again opening the contacts.However, this brief closing of contacts 89 is suicient to energizemagnet 81 thus setting up the holding circuit as set forth above.

Another condition may obtain by adding an amount, for instance 10000 onthe totalizer without disturbing the setting of the thousands element 59from its zero position. By reference to Figure 2 it will be noted thatthe rod 98 has no notches opposite the remaining stepped cams 59cooperating therewith. If any one of the higher order cams 59 be rotatedone step, the rise between the 'l" and 8 positions of said cam willimmediately rock the rod 98, shaft 94 and arm 95 clockwise to close thecontacts 89 for the above stated purpose.

The contacts 9| (Fig. 7) are normally closed in order that upon closingthe contacts 89 by the totalizer the holding circuit may be at once setup, through the magnets 86 and 81. However, it is necessary to break theholding circuit near the end of the reset cycle, hence the contacts 9|whose cam is timed to open said contacts at the proper time. Just beforethe contacts 9| open, the magnet 6| and a magnet |03 are energized bythe closing of contacts LP'I. The magnet |03 when energized closes itscontacts |04 which contacts are wired parallel to the contacts 93 thusholding the magnet 19 energized to maintain the clutches or couplings'l5 (Fig. l) in their adjusted positions until the end of the resettingmovement. The magnets 19 are deenergized by their respective camcontacts LP8, LPS and LP|0 (Fig. '7).

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification, itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from thespirit of the invention.

In a machine of the class described, the combination of a pluralityof totalizers, item entering means, total takingr means for all of saidtotalizers, automatic means to initiate a total taking operation, ,andmeans controlled by one of the totalizers to render the total takingmeans for all of the totalizers ineffective until a predetermined amounthas been accumulated on said one totalizer.

13. In a machine of the class described, the combination of a pluralityof totalizers for accu.- mulating items, totalizer resetting mechanismoperative at the ends of groups of items for simultaneously resettingall of the totalizers, and means operated by one of said totalizers todetermine whether or not the totalizers are to be reset at the end of agroup of items.

14. In a machine of the class described, the combination of a pluralityof totalizers for accumulating items, totalizer resetting mechanismoperative at the ends of groups of items for resetting all of thetotalizers, and means operated by one of said totalizers when apredetermined amount has been accumulated on said one totalizer torender the resetting mechanism for all of the totalizers effective.

15. In a machine of the class described, the combination of a pluralityof totalizers for accumulating groups of items, totalizer resettingmechanism operative at the ends of groups of items, and means operatedby one of the totalizers to suppress resetting of all of the totalizersuntil a predetermined amount has been accumulated on said one totalizer.

16. In a machine of the class described, the combination of a totalizerfor accumulating items, total taking control mechanism operative at theend of a group of items, normally inoperative total printing mechanismfor printing totals from the totalizer, a bail operable by any one ofthe totalizer elements above an intermediate order on item enteringoperations, and contacts closed by said bail to render the totalprinting means eiective.

17. In a machine of the class described, the combination of a totalizer,item entering means, total taking means, contacts to render the totaltaking means effective, and a bail actuated by any one of thedenominational order totalizer elements above an intermediate order tooperate said contacts when a predetermined amount has been accumulatedon the totalizer.
